Abstract
The present invention relates to a method for making a global LED lamp (10) having a transparent globe (14) and a base (12) for connecting to a lamp socket. By wrapping the base (12) in expansive foam tape (38) of Compriband type or similar, prior to inserting it in a neck shaped portion (16) of the globe (14), automatic alignment of the base (12) in the globe neck (16) may be obtained. Further, soft metal strips (36) may be wrapped about the tape (38) prior to wrapping the tape (38) about the base (12). The tape (38) acts as an inflatable cushion, which presses the metal strips (36) towards the base (12) and the globe (14). Improved heat transfer between the globe (14) and the base (12) may thus be obtained.
